GDL-LC

Hey gents, I've been lerking on here for a while and wanted to sign up to say thank you for the information and hard work. Could anyone help with this issue, I'm trying to install DSM 4.3 onto a HP Microserver NL36. The bootloader works until it mounts the only physical drive (the other being the 4Gb USB key with the loader) The last line of the loader before it pauses is: Attached SCSI removalable disk. If I remove the USB key, it displays that the drive was removed, so it's not hanging, it's just stopped. It finds the NIC, but the NIC doesn't get an IP (Checked DHCP) so I'm unable to proceed, Any advice? Everything is stock on the hardware, and images (I've not modifed the MAC address). Is there anyway to get to a command prompt from this point to check to see what's going on?
